Abstract

Based on the principles of geometry optics and photometry, the light energy propagating through optical fiber and monochromator has been analyzed respectively in the paper. The expressions of the utilization ratio of light energy for coupling between the common extended source and the fiber and the monochromator has been deduced theoretically. The relationships between the utilization ratio and relative aperture of convex lens, numerical aperture of the fiber, relative aperture of the monochromator and object distance are discussed. The experimental results are consistent with the theoretical analyses. The conclusions are useful and helpful for us to conduct optical experiments and utilize and choose extended source and convex lens when we work on the coupling system between the extended sources and optical fiber and monochromator.
